VIDEO : Nastia Liukin to Derek Hough: Don't Hurry Back to DWTS!

Nastia Liukin is playing hooky from school while her Dancing With the Stars partner Derek Hough recovers.
"Don't tell my professors!" she joked. "No, they know, and they're aware of the situation." Nastia is staying in Los Angeles instead of heading back to New York for school so she can work with her injured partner. While Derek works on getting back on his feet, Sasha Farber has been dancing in his place.
"Derek's definitely got some big shoes to fill?It's not the best circumstance for me to step in," Sasha said. But they've been making the best of it.??
